About four o'clock, the soil, generally composed of a thick mud mixed with petrified wood, changed by degrees, and it became more stony, and seemed strewn with conglomerate and pieces of basalt, with a sprinkling of lava.

To the conglomerate and trachyte succeeded black basalt, the first dispread in layers full of bubbles, the latter forming regular prisms, placed like a colonnade supporting the spring of the immense vault, an admirable specimen of natural architecture.

The strata are of sandstone, and one layer was remarkable from being composed of a firmly- cemented conglomerate of pumice pebbles, which must have travelled more than four hundred miles, from the Andes.
